DIE.

SPECIFICATION forming part f Letters Patent NO. 691,666, dated. `January 21, 1902.

Application filed July 23, 1901. Serial No. 69,405. (No model.)

To aZZ whom t may concern,.-

Be it known that I, ARTHUR RoGERs, of Barnesville, in the county ofBelmont and State of Ohio, have invented certain new and useful Improvements in Dies; and I hereby declare that the following is a full, clear, and exact description thereof, reference bein g had v to the accompanying drawings, which form part of this specification. ro This invention is an improvement in the manufacture of hollow-back spades, shovels, scoops, the., and has particular reference to the dies for making or shaping such shovels, dac., from sheet-metal blanks previously cut to proper form for stamping.

The invention consists in the novel con struction ofthe dies by, first, hinging them together, so that the upper die will always close exactly upon the lower die; second, making zo the upper die very heavy,so that no machinery will be needed to close the die, its own weight being sufficient to effect the shaping of the metal; third, providing such die with a grip to hold the blank during the shaping process,

and, fourth, a setting-plate for the blanks.

The accompanying drawings illustrate the die, such as used for forming hollow-back shovels or scoops.

Figure lis a side elevation of the die closed; Fig. 2, a top view thereof opened, and Fig. 3 a longitudinal sectional view through Fig. l.

Referring to the drawings, A designates the lower or male die, which is formed of heavy cast metal and mounted upon timbers B. Said die has its upper surface formed with a protuberence a, conforming to the desired face or front contour of the shovel, scoop, dac., to be made thereon, and is provided with a groove et', conforming to the contour it is desired to give the shank or tang of the shovel. The lower die also has perforated hinge-lugs d2 near its 'rear edge, asshown. The upper die O is shaped somewhat like, but reversely to, die A, having a concavity to it the pro- 45 tuberance a of die A and a projecting rib c to lit the groove a' of die A. It is also provided with hinge-lugs c2, adapted to lit snugly between and against lugs a2 of die et, and all said lugs are transiixed by the hinge-rod D, 5o as shown. The die C isalso provided with a handle C at is front end, by which it can be raised, and, if necessary, a powerful leverage can be exerted on handle O', inclosing the die,

if the blank should be insu'fflciently heatedor if for other cause the die did not close properly thereon when part C is dropped.

Between the hinge-lugs c2 a grip-lever E is pivoted on rod D, said lever having a tooth e on its inner end, which is adapted to` bite and hold the front or inner edge of the blank dur- 6o ing the pressing thereof, said grip being operated by a hand-lever E', as indicated in the drawings, Fig. 3.

The upper die may be raised by hand or power, it being very heavy, and after a suitable blank H, heated to a red heat, is placed in position over the lower die and held by the grip E the upperl die is dropped upon the lower and stamps or forms the blank between the dies into the desired shape. The hinges 7o keep the dies in exact relative position with out the employment of other guides.

In order to insure the proper setting of the blanks H, so that the tang' or shank of the shovel will be properly formed, the guideplate F may be used. This is hinged to the supports B in position to beturned down over v the grooved end of lower die B after the blank is laid thereon, and on the free edge of this plate are two lugs or guides, which are adapt- 8o ed to embrace the shank or tang h of the blank H between them, as indicated in Fig. 2, and insure the proper location of blank I-I upon the lower die. The blank is then gripped by lever E and the guide-plate F thrown back out of the way. Then the upper die is dropped and the operation is complete.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent therefor, is- 9o l. In adie for forming hollow-back shovels, dto., the combination of the lower die; with the upper weighted die hinged to the lower` die at its rear edge, and a grip for holding the blank during stamping thereof.

2. In adie for ,formingholloW-back shovels, dac., the combination of the lower die; with the upper die hinged to the lower die at its rear edge, a handle for raising said die subl stantially as described, and a grip 'for holdroov ing the blank during stamping thereof.

3'. In a die for forming hollow-back shovels,

the combination of the lower die provided with protuberance a, hollow a', and lugs a2; with the upper weighted die having,r recess c rib or projection c and lugs c2 and the rod transxing said lugs and hinging the dies together, substantially as described.

4. In a die, the combination of the lower die provided with protuberance a, hollow co', and lugs a2; with the upper die having recess, c, rib or projection c, and lugs c2, the rod transxing said lugs, and hinging the dies together, and the grip-lever pivoted between said lugs, substantially as described.

5. In a die for forming hollow-back shovels, &c., the combination of the lower die; with the upper weighted die hinged to the lower die at its rear edge, and a grip for holding the blank during the stamping thereof, and the two witnesses.
